n srIKE-MACHINE.

Specification of Letters Patent No. 11,225, dated July 4,. 1854.

`To all whom it may concern l Be it known that I, FnN'roN HUMrHREY, of Boonton, in the county of Morris and State of New Jersey, have invented a new.

and useful Machine for Making `Ship and Boat Spikes; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference `being `had to the annexed drawings, making a part of this speciication, in which- Figure l is a perspectivewview; Fig. 2 `a transverse section taken through the center of the lever F. l To enable others skilled in the art to make y and use my invention I will proceed to describe its construction and operation.

/A is themain driving wheel and gears into the wheel B. y

C C are wrought iron shafts.

D isa cutting lever.

E is a cam.

` F is a grippinglever.

Gr is a cam.

I-I isa pointing lever. I is a gage lever. l

J is a motion for the gage.

L is a heading lever.

M is a cam.` y

N is a gear wheel and gears into the wheel O. -i y T J are bevel gear wheels..

S S S S is the bedpieceor framework.

a is a square cutter.

o is a concave die.

c is a grooved roller.

Z is a concave cutter.

e is a moving die.

f is a stationary die.

g is a gage (see wire).

h `is a header.

j is a tongued roller and is fitted to the roller e.

In sectional drawing, Fig. 2, C represents the end of a shaft, F a gripping lever, G a

` cam, I the gage lever, e the moving die, f

stationary die, g the gage, If the die boX.

OperatiowFirst, see that the marks thus on the` bevel wheels T J come together; then turn the wheel B until the motion J raises the leverI. Then suppose a rod be admitted between the rollers j o against the gage g, (turn alittle more,) then the lever D would be forced up by the cam E, and the rod would be severed by the cutters CZ a. Then turn a little more and the lever H forces the rollers j c together, thus the poi-nt is made, and the spike is landed into the die box. (See sectional drawing maked thus f.) Then turn a little more and the lever F is raised by the cam Gr which grips and firmly holds the spike; when the lever L is forced forward by the cam M and makes the head; and so on to another revolution.

AdoantageaSome of the advantages in this machine are:

First. It makes one spike at each revolution.

Second. It points immediately after the rod is cutoff, while the iron is hot.

Third. A long or short point can be made by changing the cam K a little forward or back, and slightly altering its form.

Fourth. A round head can be made on a square rod simply by rounding the rod at the end'. This is done by the pressure o'fLth'e concave cutter d, against the concave die b, as the rod is cut off, which may be illustrated by the above sketch in which, F ig. 1 represents the rod as seen endwise as it is being cut off, and is marked a; b represents the moving cutter, and c the concave die which in Fig. 2 are represented closed together showing the manner of rounding. Hence in practical results, the thickness of the die and cutter, must be just equal to the length required for a head. By this rounding process, I am enabled to make the proper deckspike, which is made from a square rod, with a round flat head; and which has long been desired.

Fifth. A change in the place of labor on the rollers 7' o is effected by making the wheel N a litt-le smaller than the wheel O, hence while O makes one revolution N will make a little'more than one revolution, and thus bring a new place of labor into use at every revolution until the whole surface of the rollers are'evenly worn and may be illustrated by the above figures, in which A B represents two pointing rollers. Then Ain operation, suppose the first point to be made on a section marked a. As the rollers changev the place of labor, the second pointwould be made on, or at, section b; the third at section o, and so on until the whole circumference of the rollers were truly worn. .For as the point of a spike only requires about one inch of surface, and as therollers j c are about 13 inches in circumference, then nearly l2 tinies as many spikes can be made l is raisedby the ca1n`K which gradually i tain a change in the place of labor on the rollers at every revolution, as above shown and described.

2. The general construction, arrangement and combination of the levers, for the 15 above specified purpose.
